- 6.0." tition 75 Ycovers all of the wiring and conboss 33 is formed in each cavity 29 and ex-v tending through each boss 33 is a central stud 34 which extends through the block 21 andv secures a bus-bar) 35 in a recess36 formed in the bottom of the block 21. My invention provides a single bus-bar 35 throuo'h whicheach of the central studs 34 extends. The end 38 of the bu-s-bar extends beyond the fuse block 21 and is adapted to have a. wire attached thereto, as clearly shown in Figs. 3 and v5. ,The block 21 alsov provides a main fuse socket 40. As clearly` shown in Fig. 4, the lmain fuse socket 40 provides a shell 41 which isretainedy in av also provided to 'assist insecuring thev bar- 48 in place.

A bolt 51 extendsy through an opening .Y formed yin the outer endof th'ebar 4.8,Y this vholt 514 extending through a clevis 52 for pivoting a knife 53 of a switch to the bar 48.

The clevis 52 has legs 5 4 which extendto eachsi'de of the end of the bar r48. On the opposite end of the knife Contact 53 there iQ formed a clevisl 56 betweenwhich asta.- tionary contact 57 extends when the switch is in closed position. An arm 58 is attached to the knifecontact 53, this` arm extending upwardly andy having aknob 60 attached.'

vrent is utilized. The other circuit Wires 0f thereto, as clearly shown in Fig. 5. The knob 60` is placed concentrically with the point of pivotvof the knife contact 53. The

knob 60 is especially preparedv so that the upper portion thereof is in the shapeofran arrow 61,l as clearly shown in Figs. 1 to 3, inclusive. l f l' The stationary contact 57 is secured in a vrecess 64 formed in the lower face of the lock 21 by screws 65 which extend throughr a flangev 66 of the block 21.

y The rear portion of thestationary contact 57 is bent upwardly at 68 and extends throughA av lslot 69 formed in the flange 66. The contact is bent horizontally at 70 through which por,-

tion 70 a screw 71 extends for securing a wire thereto. v i

Extending across the box 11 is a front or partition 75. Y This partition is .secured Y to the block 21 by means `of nuts 76 which thread onto studs/7 7 extending from formations 78` of the `'block 21. Thepartition has an opening 80 through which the upvper portions of the circuit sockets 27 and the main socket 40 extends, as clearly shown 1n F1gs.2 and 4 of the drawing.` Thisy partacts of the' switch and prevents a person from touching` alive part. f.

.The coveryf12 is-depressed at 82 and has' arrow portion 61 ofthe knob 60 extends .through and may be operated from the exterior of the box.

One main line is` connected to the stationary contact- 57 by the screw 71. vThe other 'of the main lines is vconnected to a plate 85 by a screw 86. The plate is secured in place, as shown in Fig@ 5, by screws V87 which extend through( the flange 66.0f the fuse block 21. The plate 85 has a screw 88 .the fuse socket 40'through' the contact plate 44gwhich`iis associated with the-shell 41.

A Vwire tothe meter'is connected to the contactplate 44 by a screw 92. A wire from thel meter is connected to the `end 38 of the bus-bar 35by a screw-93. Current is supplied by the bus-bar 35 to each ofthe circuit fuse sockets A27. Current passes from" each 'of 'the fuse'socket's 27 through' the contactplates" 32. A screw 94 is provided for attaching a circuit wire to each ofthe contact plates 32. These circuit wires extend from the box 11 to devices where the curthese subsidiary circuits areV extended into the box and connect toa cont-act plate 96 by means of-screws 97. Thiscontact` plate 96 issecured tothe flange 66 of the fuse block rlfbyv screws y98. A screw 99V is provided for 4securing a wire` which extends from the meter to the contact'plate`96.

The bridge 18 is removed by loosening4 bridge. 'The fuse block 21, due to the re? movability thereof, may be wired before its installation inthe box 11. This makes the wi ring thereof Very easy. The circuit wires, if *desired,. may be extended through the Aspace below the raised portion 22of the bridge 18. The bridge 18 will hold these wires iny place and prevent them from interfering with the switch.

n The partition 75 entirely covers the livev parts'of the service switch and'exposes only thec'ircuit sockets and the'main socket. The partition is marked On and Off, asindicated at 100 Vand `101. The. arrow on the `knob 60 is j arranged so. that the lswitch is closed when it .points tofOnL and open when itpoints .to Off. .f The'cover 12 is also marked/W011i and Offas indicated at 103 and 104. By such marking, it is possible to discern whether or not the switch of the service switch is open.

By providing a switch which works in a plane parallel to the front of the box, and by arranging it to the side of the fuse block, any interference the-reto by the wires is eliminated. By arranging the knob in the iront of the box any extensions from the sides of the box are done away with and the box may be set in the wall. 'Ihis is a very valuable feature, as the box may be set in an unobstructing place which is sometimes very desirable. By providing the depression 82 and the opening 83, the knob 60 may be conveniently operated even though the cover 12 is closed.

I claim as my invention:
